求翻译：有人说，地球的颜色是绿色的，她孕育着生命，预示着人类的诞生和未来。我说，她是生命的摇篮，人类的母亲，她把全部的爱无私地奉献给人类的子子孙孙。她的确很大，幅员辽阔，但不是无边无际；她的确很美，山青水秀，但不是青春永远；她的确很富，资源广博，但不是取之不尽，用之不竭。是什么意思？

It is said that green is the color of the Earth, she is pregnant with life, heralded the birth of humanity and the future. I say, she is the cradle of life, human mother, she unselfishly dedicate all my love to future generations of mankind. She did great, vast, but it's not endless; she is beautiful, clear waters and green hills, but not young forever; she is rich indeed, resources varied, however, is not inexhaustible, always available.
